A Body Spatial Dimension Mapper (BSDM) comprising a body mapping booth (10), an array of laser range detectors mounted on the top (17) and bottom (18) of the booth, a moveable circular sensor ring (11), a sensor controller and processing unit (13), and a media production unit (14). The BSDM provides a highly automated and accurate method for determining 3-D surface measurements of a human body, a digital representation of the body shape, contour, length, width, and volume measurements, and a digital format of these measurements for storage, transmission, and computer processing. It is applicable to the garment, online clothing retail, and medical industries.
